Find parametric equations for the line through $𝑃_0=(9,−1,1)$ perpendicular to the plane $10𝑥+12𝑦−4𝑧=10. 𝑥=9+10𝑡$

calculusgeometrylinear algebravectors

How would I find the parametric equations for the line through $𝑃_0=(9,−1,1)$ perpendicular to the plane $10𝑥+12𝑦−4𝑧=10.$?

Given:
$𝑥=9+10𝑡$

What is $y$ and $z$?

So first what I do is find the normal vector to the plane which is as follows:
$\left\langle10,12,-4\right\rangle$

Then I used that to find the parametrization of the line: $𝑃_0=(9,−1,1)$

and so I get $y=-1+12t$ and $z=1+-4t$.right or wrong

The direction vector for this line is $v=(10,12,-4)$ (i.e normal vector is $N=10i+12j-4k$) and it must pass through the point $P_{0}=(9,-1,1).$

Thus we have parametric equations $$(x,y,z)=(9,-1,1)+(10,12,-4)t=(9+10t,-1+12t,1-4t).$$
